COMBINED CONDENSING AND FEED-WATER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 506,292, dated October10, 1893.

Application filed January 31, 1893. Serial No. 460,224- (No model.)

To all whom it may concern:

Beit known that we, FREDERICK MERIAM WHEELER, of Montclair, in thecounty of Essex and State of New Jersey, and GEORGE W.

LYON, of Norwich, in the county of New London and State of Connecticut,citizens of the United States, have invented an Improvement in CombinedCondensing and Feed-Water Apparatus, of which the following is a specitofication.

In connection with engines, especially those employed on steam vessels,it has been found advantageous to make use of a separate steam engine todrive the water circulating pump for supplying the condensing water tothe condenser and an air pump also operated by the same engine formaintaining the required vacuum in the condenser, and a separate feedwater pump has beenemployed for taking the water of condensation fromthe condenser and returning it to the boiler. In this case however theexhaust steam from the engine of the water circulating, air and feedpumps has either passed into the condenser or else escaped into theatmosphere, involving the loss of the water of condensation and of theheat in such steam.

In the present improvement We make use of the feed water from thecondenser as a means for condensing the steam from the engines thatdrive the water circulatingand other pumps, so as to prevent loss ofwaterand of heat, and to this combined condensing and feed waterapparatus our invention 3 5 relates.

In the drawings, Figure l is an elevation partially in sectionrepresenting our improvement as adapted to a vacuum outfit. Fig. 2 is asimilar view with the parts adapted to a 40 non-vacuum outfit. Fig. 3 isan elevation partially in section of the present improvements with anengine and pump differently arranged. Fig. 4 is a plan View with thecoudenser removed, and Fig. 5 is an end eleva- 5 tion of the engine andcondenser with the feed Water pump and hot well removed.

The condenser A is of any desired charac-' ter and the pump B, Fig. l,is adapted to circulate water through the condenser, the water supplypipe is shown at 2 and the dis- 5o charge pipe 3 takes the warm wateraway from the condenser, and Iis the pipe passing the exhaust steam intothe condenser. This present improvement is specially adapted to tubularsurface condensers, but the same may 5 5 be availed of with jet or otherkinds of condensers.

The piston of the steam engine cylinder C, Fig. 2, is connected to thepiston of the pump B by the piston rod 5, and steam is supplied to thecylinder C by a suitable pipe such as the pipe 6 to the valve chest, andD is the steam cylinder 'for driving-the feed Water pump E; and weremark that these pumping engines are to be of any suitable constructionand they may be arranged in whatever position is most convenient for thecondenser.

In Fig. 2 we have represented a hot well and filter tank G as below thecondenser'for the, water of condensation to run into the hotwell filtertank, and there is a perforated par-- tition 7 upon which is suitablematerial such as sponge for the absorption of oily materials, and thewater drips through the perforated partition 7 to the bottom of the hot.well from which the pipe 8 leads to the pump E, and the pipe 9 from thepump is carried to the boiler that is to be supplied with feed water.The pipe 10 from the steam cylinder D leads into the hot well. So alsodoes the pipe 11 from the steam cylinder 0, and these connections aremade below the perforatedpartition 7, so that the water running throughsuch perforated partition serves as a jet condensento condense the steamfrom the cylinders C and D, thus saving the loss of heat and of waterthat would result if the exhaust from the cylinders C and D passed intothe atmosphere, and the feed water which is returned by the pump E tothe boiler is raised to a higher temperature than the water passing fromthe condenser. Hence the consumption of fuel in the boiler is less andthe hot well is kept at as high a temperature as consistent with thepumping operation. 9 5

I In Fig.1 the air pump H is represented in. addition to the partsbefore described, and the stem cylinder C is made to act bothupon thecirculating pump B and the air pumpH; and the Water of condensation fromthe air pump H is taken to the filter tank and hotwell G, and in thisfigure We have represented the hot-well as having an upper and a lowervessel connected by a cock 12, the Water of condensation passing intothe upper vessel and through the cook 12 to the lower vessel G in whichis the perforated partition 17 which causes the water to descend in jetsto condense the exhaust steam passing by the pipes 20 and 21 from thecylinders O and D respectively. By this means the same benefit isderived by the condensation of the steam made use of in operating thepumping engines; and we remark that the feed water pump E and the steamcylinder thereof are the same as shown in Fig. 2, only they arerepresented at the other end of the condenser.

In Figs. 3, 4 and 5 the parts are represented in a more compact formthan in Fig. 1,be-

cause we have shown the filter tank andhotwell G3 as well and the airand circulating pumps and the engine as below the condenser, and thesteam cylinder 0 that drives the circulating pump B is connected by across head 18 with the piston rods 19 of the air pumps 11', and theseair pumps receive the water of condensation by the pipes 23 from thecondenser, and the water of condensation is passed by the pipe 24: tothe filter tank and hot-well G above the partition 27, and the exhauststeam from both the cylinders C and D is passed by the pipes and 31 andcondensed in the hot-well for increasing the temperature of the feedwater and utilizing the steam and saving Water.

The before mentioned improvements are available with engines for bilgewater or other pumps, the steam from such separate engines being takeninto the hot-well as before set forth.

\Ve claim as our invention- 1. The combination with the surfacecondenser, water circulating pump and steam engine for actuating thesame, of a hot-well, a filter tank above the hot-well and its chamberand a pipe from the chamber to the engine and in which chamber the feedwater acts to condense the exhaust steam, substantially as set forth.

2. The combination with the surface condenser, water circulating pumpand steam engine for actuating the same, and a feed water pump, of ahot-well, a filter tank above the hot-well and its chamber and a pipefrom the chamber to the engine and in which chamber the feed-water actsto condense the exhaust steam from the engine, substantially as setforth.

3. The combination with a condenser, of a water circulating pumpdirectly below one end of such condenser, of a steam engine also belowthe condenser for actuating such pump, an air and Water pump fordischarging the water of condensation, a filter chamber containing asponge or similar material and having a perforated bottom, a hot-wellbelowthe same, a pipe for connecting the air and water pump to thehot-well, and a pipe for passing the steam from the engines of the pumpsinto the chamber of the hot-Well below the perforated partition,substantially as set forth.
